Poor Alice and Bob. Always exposed. Always out there. Never left alone. ❤️
-
The analogy with colors in this video is pure genius! Thank you guys, this was an amazing introduction to Diffie-Hellman!
-
yessss him again
-
5 years later and this is still done a million times a minute out there. Very well explained, thank you!
-
Random squirting of fluids... exactly what I wanted to see this early in the morning...
-
Nice! This is a subject I should have covered immediately after the Public Key Cryptography video, since that one lays out the problem of exchanging keys that Diffie-Hellman solves. Great to see such a clear explanation, I doubt I'd have gone to the effort to get coloured liquids!
-
Watched the defcon presentation from years ago given by the creator of the diffie-helman key exchange... It was absolutely fascinating. Dude is an innovator and pure genius. Seems like a nice guy as well

1:04 First rule of cryptography: Unless your job is to create cryptographic algorithms, never implement your own cryptographic algorithms. You will screw it up.
-
I really like this guy. Been watching and rewatching his lessons for like 3 hours.
-
How curious, PBS Infinite Series have been talking about encription in the last few days. Now I've got double the encryption bonanza! This has been a good week.
-
I'm a simple man. I see a computerphile video with Mike Pound, I click like
-
This demonstration was a classic Parker square.
-
What I like most about this channel is the ability of the presenters to explain things simply without mathematics. That is real teaching, not reciting formal proofs and equations
-
Excellent, clear explanation, and the colours really showed the process visually, thanks guys!
-
i love the style of the whole channel! proofs nobody really needs power point or laborious anmations.
-
Everytime I feel confused by e2ee or key exchange, I will come back and see these videos. Really helps.
-
Sir, you have sincerely helped me with my homework far more than my textbook ever could. Thank you so much for making these videos! :D
-
This helps soooo much with my university studies! Dr. Pound, your the best.
-
Great explanation. Makes this concept really easy and straight forward to understand. 👍Thank you
-
Such a good video! Really clever concept, and the colour analogy is great! Cheers! :D
